(1) Oil filter (8) Transmission case (20) Transfer gear case (21) Magnetic screen (22) Scavenge screen for transfer gear case (23) Transmission charging pump section (24) Transmission scavenge pump sectionInlet oil to transmission charging pump (23) comes from the reservoir of differential and bevel gear case (18) . The oil is drawn through magnetic screen (21) to transmission scavenge pump (23) . The oil flows through oil filter (1) . The oil is then sent to upshift solenoid (2) or downshift solenoid (3) , as required. The oil now flows to priority valve (4) of selector group (5) . This oil now divides. Some of the oil flows to pressure control group (7) for transmission clutch engagement. The remainder of the oil from selector group (5) flows to torque converter (25) .Transmission scavenge pump section (24) draws oil from transfer gear case (20) and reservoir (19) . This oil flows through screen (22) and transmission scavenge pump section (24) . From the transmission scavenge pump section, the oil flows to the reservoir (18) for the differential and bevel gear case.

The oil from the oil cooler flows through line (29) and splits into two lines. Some of the oil flows through line (31) in order to lubricate the flywheel. Some of the oil continues in line (29) to transmission case (8) for lubrication.Pump section (23) draws oil from the reservoir for differential case (18) . This oil flows through magnetic screen (21) , pump section (23) and oil filter (1) . From the oil filter, the oil flows to upshift solenoid (2) , downshift solenoid (3) and priority valve (4) .Oil in the reservoir for flywheel case (14) flows through scavenge screen (17) , scavenge pump (16) and line (12) . The oil then flows to drive shaft bearing (10) .
